During the summers of 2017 and 2018, Alaska Volcano Observatory (AVO) geologists from the University of Alaska, Fairbanks (UAF), the U.S. Geological Survey (USGS), and the Alaska Division of Geological & Geophysical Surveys (DGGS) conducted fieldwork at Pavlof Volcano (55.4173 N, -161.8937 W), on the Alaska Peninsula, Alaska. The fieldwork was conducted in support of geologic mapping and tephrostratigraphy, to improve the documentation of recent Pavlof eruptions, and to better assess hazards associated with Pavlof eruptions. As a result, samples of lava and various pyroclasts (mainly bombs and lapilli) were collected for whole rock geochemistry analyses. This report includes whole rock major- and trace-element data from lava and bomb samples from the 1996, 2013, 2014, and 2016 eruptions, along with samples of lava and lapilli fall deposits, presumed to be of Holocene age, collected from outcrops around Pavlof and Pavlof Sister volcanoes. We also include electron probe microanalyzer (EPMA) data from tephra glass samples from the 1986 (AT-2822), 1996 (AT-2823), 2007 (AT-2824), and 2013 (AT-2821) eruptions. These samples were initially analyzed at the USGS office in Menlo Park and were re-analyzed for this report in the Advanced Instrumentation Laboratory (AIL) at UAF for comparison. Tephra EPMA glass data from the 2016 eruption, analyzed in the AIL, is also included from sample AT-3680. The analytical data tables associated with this report are available in digital format as comma-separated value (CSV) files. Users can access the complete report and digital data from the DGGS website: http://doi.org/10.14509/30580. This investigation was conducted in support of geologic mapping and tephrostratigraphy, to improve the documentation of recent Pavlof eruptions, and to better assess hazards associated with Pavlof eruptions. We thank Maritime Helicopters and pilot Jared Berman and Egli Air Haul and pilot Sam Egli for efficient and safe transportation in the field. We thank Mary Martin and the Cold Bay Lodge staff for comfortable lodging and excellent meals during our fieldwork. Thanks to Ken Severin for making the UAF AIL facility an excellent analytical resource for AVO EPMA analytical work. Max Kaufmann collected ash samples 16PVMK001a and 16PVMK001b analyzed for this study. The AVO tephra analytical routine was created by Matt Loewen (USGS/AVO), Kristi Wallace (USGS/AVO), and Nathan Graham (UAF) and we are grateful for their efforts to standardize the AVO glass EPMA analytical protocols.

Dense lava flow and juvenile bomb samples were collected using a sledge hammer, and where possible the samples were chipped in the field to select clean interior regions of the samples for analysis. Some of the flows and bombs were too hard to efficiently chip in the field, and were chipped in the lab after fieldwork was finished. Juvenile samples from the coarse lapilli tephra fall deposits were prepared in the lab after fieldwork was completed. 2016-01-01T00:00:00 Sample preparation and analysis - Samples were analyzed for whole rock major- and trace-elements. A subset of tephra glass samples were also analyzed by electron probe microanalyzer (EPMA). Many of these samples were initially analyzed at the USGS office in Menlo Park (Waythomas and others, 2017) and were re-analyzed for this report in the Advanced Instrumentation Laboratory (AIL) at UAF for comparison. The accompanying report describes sample preparation and analytical methods in detail. 2020-01-01T00:00:00 otherRestrictions Metadata Use Constraints: If the user has modified the data in any way they are obligated to describe the types of modifications they have performed in the supporting metadata file.
